Which of the following statements are correct or incorrect according to the Bohr’s atomic model? Give a reason for each statement. (i) Electrons lose energy while moving in fixed orbits and slowly fall into the nucleus. (ii) Electrons can exist anywhere around the nucleus with no fixed energy. (iii) Electrons revolve around the nucleus in orbits of fixed energy without losing energy. (iv) Electrons can be found between energy levels as they move around the nucleus.

Statement (iii) is correct because electrons occupy discrete stationary orbits without radiating energy. Statements (i), (ii) and (iv) are incorrect because electrons possess fixed quantized energies and cannot spiral inward or exist between allowed levels.
